I'm going to presume you're correct. I'd never tried this on Tinder, the place felt so vanilla I just didn't feel like it would be right doing such a thing.
Well clearly I need a throw away also. Also an Australian in late 40's.
There was a golden age a while back using websites such as AMM for hookups and threesomes, and Fetlife was unusually great for kink. I basically just listed myself as a male into needle play (with equipment) and LOTS of girls actually came to me. I would get messages asking if my lab was real and when they could visit. Which is a completely contrast to anything you'd see today.
Fetlife really died. The vast majority of female accounts have some variation of "if you'd like to talk to me more, subscribe to my Onlyfans". I opened my inbox today and clicked on the profiles of girls that messaged me years ago, they've all left the site, and you absolutely can't replicate that experience on Tinder.
